DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, a quick-release filter element structure includes a top cover 2, a shell 3 and a filter element body 4. The filter element body 4 is placed in the shell 3, and the top cover 2 is detachably connected to the shell 3;

[0022] The filter element body 4 has an annular protrusion 41, and a plurality of first clamping posts 42 are arranged at the bottom of the annular protrusion 41 along the center of the filter element body 4. A first clamping groove 31 matching the first clamping post 42 is provided on the top of the housing 3; the housing 3 has a bottom plate 32, which has a first through hole 33, and a plurality of second limiting posts 321 are arranged on the bottom plate 32 along the center of the first through hole 33. A filter element base 43 is fixed to the bottom of the filter element body 4, and the bottom of the filter element base 43 has the same number of second limiting grooves 431 as the plurality of second limiting posts 321. The second limiting posts 321 are engaged with the second limiting grooves 431 to limit the position.

[0023] The top cover 2 has a second through hole 21, the filter element body 4 has a first through tube 44, the first through tube 44 passes through the second through hole 21, limiting blocks 51 are installed on both sides of the top cover 2, and limiting seats 52 are installed on both sides of the outer wall of the filter element body 4. An unlocking component is also installed on one side of the limiting seat 52, and the limiting block 51 has a first connecting piece, and the limiting block 51 is limitedly engaged with the limiting seat 52 through the first connecting piece.

[0024] The top cover 2, the outer shell 3 and the filter element body 4 are arranged on the same axis.

[0025] With the above structure, the filter element main body 4 is detachably placed in the outer shell 3, and the top cover 2 is detachably connected to the outer shell 3 to cover the filter element main body 4. The top cover 2 can be fixed to the outer shell 3 by the first connecting piece on the limit block 51. At the same time, the first connecting piece is released from the outer shell 3 by the unlocking component provided on the limit seat 52. The top cover 2 is reopened and the filter element main body 4 in the outer shell 3 is quickly pulled out and replaced. The disassembly and assembly are convenient, and the replacement is more convenient. At the same time, the first clamping groove 31 provided on the top of the outer shell 3 is clamped and limited with the first clamping column 42 of the filter element main body 4, and the second limiting groove 431 of the filter element base 43 is clamped and limited with the second limiting column 321 of the bottom plate 32, which is conducive to more secure fixation. At the same time, the structure is stable, and it is not easy for the filter element to be offset during installation, and the installation accuracy is high.

[0026] Specifically, if Figures 1 to 4 As shown, the first connecting member includes a first spring 511 and a clamping block 512 , the limiting seat 52 is provided with a third clamping groove 521 , the third clamping groove 521 has a fourth clamping groove 522 , and the clamping block 512 is clamped in the fourth clamping groove 522 .

[0027] The unlocking assembly includes a limit frame 61, a pressing rod 62, a second spring 63 and a push plate 64. The limit frame 61 is installed on one side of the limit seat 52. A pressing channel 611 is opened in the limit frame 61. The pressing channel 611 is connected to the third clamping groove 521. The pressing rod 62 passes through the limit frame 61 and is fixed to one end of the second spring 63. The other end of the second spring 63 is fixedly connected to the push plate 64. The push plate 64 is in abutment against the clamping block 512 and is used to push out the clamping block 512 during disassembly.

[0028] When the top cover 2 is mounted on the shell 3, the pressing rod 62 is pulled outward to make room for the fourth clamping groove 522, and the limiting block 51 is inserted into the third clamping groove 521 of the limiting seat 52. Since the fourth clamping groove 522 is provided, the fourth clamping groove 522 is wider than the third clamping groove 521. When the clamping block 512 is inserted into the third clamping groove 521, the first spring 511 contracts. When the clamping block 512 enters the fourth clamping groove 522, the first spring 511 returns to its original state, pushing the clamping block 512 into the fourth clamping groove 522, completing the clamping connection between the top cover 2 and the shell 3. When replacing the filter element, the pressing rod 62 is pressed inward. At this time, the pressing rod 62 drives the second spring 63 to press in the direction of the fourth clamping groove 522. At this time, the force received by the second spring 63 is transmitted to the push plate 64, which presses the push plate 64 against the clamping block 512 and pushes the clamping block 512 into the fourth clamping groove 522. The first spring 511 contracts. At the same time, the user pulls out the top cover 2 after both pressing rods 62 are pressed in, thereby taking out the filter element body 4, which is conducive to quickly pulling out the filter element body 4 in the replacement shell 3, making disassembly and assembly convenient, and replacement more convenient, simple in result, and easy to use.

[0029] like Figures 1 to 4 As shown, a plurality of sliding bars 71 are arranged around the second through hole 21 on the inner cavity wall of the shell 3, and a plurality of sliding grooves 72 matching the sliding bars 71 are also provided around the filter element body 4, and the sliding bars 71 slide in conjunction with the sliding grooves 72.

[0030] The sliding bar 71 set on the inner cavity wall of the shell 3 and the sliding groove 72 set around the filter element body 4 slide together, which is conducive to replacing the filter element body 4 and making it more convenient to place the filter element body 4 into the shell 3. The filter element body 4 can be quickly inserted to improve the efficiency of replacement.

[0031] like Figures 1 to 4 As shown, the housing 3 further has a step portion 81 , on which a sealing gasket 82 is mounted. The filter element body 4 further has a protruding surface 83 , which abuts against the sealing gasket 82 on the step portion 81 .

[0032] The provision of the sealing gasket 82 is conducive to strengthening the sealing effect between the filter element body 4 and the housing 3 . At the same time, the protruding surface 83 abuts against the sealing gasket 82 on the step portion 81 , thereby strengthening the connection and fixation between the filter element body 4 and the housing 3 .

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is to include three solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution in which both A and B are satisfied. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
